Introduction: Coronary heart disease and its etiology are complex socio-medical and clinical problem in this century. World Health Organization defined coronary artery disease as acute and chronic heart ailments due to disruption of flow and myocardial blood supply. Diseases of the cardiovascular system in spite of preventable risk factors are responsible for approximately 50% of all deaths in the developed world, and this ratio is higher in developing countries. Risk factors: Coronary heart disease risk factors can be divided in those which are not preventable such as: personal and family history of cardiovascular diseases, age and gender and preventable risk factors including: high blood pressure, elevated blood cholesterol, smoking, reduced physical activity, elevated blood sugar, increased body weight, alcohol use, psychosocial factors and nutrition. There are also newly emerging risk factors which includes increased homocysteine, thrombogenic and inflammatory factors. Prevention of coronary heart disease risk factors: The concept of risk assessment factors, their reduction, initially begun in the Framingham Heart Study and refined in other models. Primary prevention relates to changing lifestyle and influencing preventable risk factors. Numerous studies and meta-analysis showed that lifestyle modification, risk reduction factors, particularly by changing diet, stopping smoking, increasing physical activity, blood pressure control can be effective in the prevention and reduction of coronary heart disease. Primary health care physicians i.e. family physicians need to take an active role in assessment of risk factors for coronary heart disease. Conclusion: The data in this paper, based on the findings from other studies, suggest the importance of using a modified algorithm in order to estimates the overall risk of coronary disease in high-risk groups among the patients in the primary health care settings..
